The 2021 GLC 300 AMG Line is a genuinely reliable proposition, with a 92.8% first-time pass rate that sits 12.8 points above the UK average—and dangerous defects are rare, occurring in only 2.9% of vehicles tested. This is a car that consistently passes MOT with minimal fuss.
At 35,000 miles on average, these vehicles are running low enough mileage that wear isn't yet a significant concern, and the 0.16 failures per car tells you serious problems are uncommon. The 1.5 advisories per vehicle suggest minor maintenance items crop up, but nothing alarming—when you're shopping for one, just budget for routine servicing and have a pre-purchase inspection confirm the service history is complete.
